Detailed Description
Amanda Demopoulos watches a s deck crew members Knott and Cornell deploy the CTD at Pea Island B. The CTD collects conductivity (salinity), temperature, and depth (pressure) data, plus it has sensors to detect dissolved oxygen, chlorophyll, and turbidity (particles in the water), as the instrument travels down to the seafloor. The CTD is also equipped with a rosette of Niskin bottles, which are specially designed water bottles that can be triggered to collect water at set depths.
